AbstractDuring 2024-2025, we continued a long-term research project to monitor the migration behavior and survival of wild juvenile spring/summer Chinook salmon Oncorhynchus tshawytscha in the Snake River Basin of Idaho. Wild parr were collected in natal tributaries, implanted with passive integrated transponder (PIT) tags, and released near their respective collection sites. In this report, we present data and analyses from detections of fish tagged in summer 2024 and monitored through spring 2025. Comprehensive detail on fish collection and tagging is described in our report of December 2024, Monitoring the migrations of wild Snake River spring/summer Chinook salmon juveniles: Fish collection and tagging, 2024. Our analyses included estimates of survival from release to instream monitoring systems and from monitoring systems to Lower Granite Dam (LGD). These estimates are summarized in Table 1. For both stream populations sampled, we estimated detection and survival estimates from release to
